Doctors in New Zealand and overseas have been targeted by a scam offering them fake jobs.
Bosses at Nelson Marlborough Health have fallen foul of a phishing hoax which has seen healthcare professionals in New Zealand and India sent bogus emails.
The emails includes phony job offers or application forms that ask for money to be sent to process visa applications.
The DHB have warned people to be on their guard and to ignore any suspicious emails.
A Nelson Marlborough Health spokeswoman said any job offers made outside their formal recruitment process would be fraudulent.
People are being asked to send money for a visa application or other costs.
"This is an illegal phishing attempt and these emails should be ignored. If the offer has been sent to your work address, you should report the scam to your IT department.
"Nelson Marlborough Health does not send job offers to people who have not actively applied for a job through our formal recruitment process.
"This means that if you haven't applied for a job directly via our online careers site, and you receive an offer, it will be a fake phishing attempt," she said.
Phishing is when someone tries to trick you into providing personal details via email or text.
The Ministry of Business, Innovation and Employment (NZ) highlighted a similar scam in New Zealand in 2017.
Scammers pretended to be senior executives, targeting victims with offers of fake jobs in their New Zealand companies.
Nelson Marlborough Health chief executive Peter Bramley said the scam had first come to light in April last year.
Fake job offers have been sent out to health professionals claiming to be from Nelson Marlborough Health.
"We were made aware by the members of the public who were checking the validity of fake job offer documents sent to them.
"Please ignore the emails and don't open any attachments. Nelson Marlborough Health does not send job offers to people who have not actively applied for a job through our formal recruitment process.
"Please check our website (www.nmdhb.govt.govt.nz) for the validity of the vacancy," he said.
Anyone who thinks they may have been offered a fake job should report the scam to New Zealand's independent, non-profit online safety organisation Netsafe.
